Abstract

We associate to a scheme X smooth over a p-adic ring a kind of cohomology group Hifp(X, j). For proper X this cohomology has Poincaré duality hence Gysin maps and cycle class maps which are reasonably explicit. For zero-cycles we show that the cycle class map is given by Coleman integration. The cohomology theory Hfp is therefore interpreted as giving a generalization of Coleman's theory. We find an embedding H2isyn(X, i) → H2ifp(X, i) where Hsyn is (rigid) syntomic cohomology. Our main result is an explicit description of the syntomic Abel-Jacobi map in terms of generalized Coleman integration.
